![]() I went through an entire month testing every imaginary combo of RTX3090 undervolting (higher and lower), and those values are certainly the sweetest spot (fully stable, cool and performant) that I've stress tested in benchmarks and games so far (also DCS) - at least with my EVGA RTX3090 FTW Ultra.Įxpect very small but noticeable performance gains (~5%), all the while you're running far lower voltage (~100W less) and quite a bit cooler (over 10✬ cooler).įor example, with Heaven Benchmark Ultra. So, that translates to +748 in the memory value with MSI Afterburner.ĭoing this puts it right in the ballpark for what Micron GDDR6X is rated for from factory (21.0 Gbps effective) - good gains added, no stability issues.įrom there on, it's all diminishing returns. You can also overclock your memory upto 1312 Mhz (that's 20.992 Gbps effective). Note that the stock memory is 1219 Mhz (19.5 Gbps effective). Blender official benchmark can take a while if you run the full load though. Realbench stress test is just GIMP photo editiing, video rendering, luxmark (gpu), and multi-tasking on a loop, which is still great, just missing 3D rendering workloads. If necessary to adjust core values for whatever reason, decrease/increase in steps of 15 Mhz, in the core clocks graph curve of MSI Afterburner. Because Blender has cpu 3D rendering and its used for animation, making video games, and more. Wait until your GPU temps have stabilized the GPU temperature has been sitting at the same value for more than 5 minutes. Open Superposition 8K in the Game mode and run the benchmark in a loop through the Cinematic button. Set also the power limit at 107% with MSI Afterburner (don't worry, it won't overheat or consume more -quite on the contrary- it's just for safe margin). Open MSI Afterburner and press Ctrl+F to bring up the curve editor. ![]() Try one of these two (or similar) on your RTX3090 (non Ti) using MSI Afterburner.: My asus 3080ti TUF on stock clocks boosts up to about 1800-1850mhz whilst pumping up to 1080mv into it, with a 975mv undervolt I can set the clocks to 2040mhz and it sits there pretty consistently and temps are around 65☌. Rinse and repeat till you find the sweetspot balance of power, heat and performance. Test it, if it's stable and you're happy with the temps/power then try increasing the clock speeds by dragging the same voltage point up by 15-20mhz. So if you're achieving 1950mhz on stock settings, lower the entire cuve and then select the curve point at 950mv and drag it back up to 1950mhz, hit apply and then it should flatten the curve after 950mv. Not quite, find the clock speeds and voltage that you're achieving on stock settings, lower the entire curve as much as possible (using the core clock slider) and then use the curve editor to drag the same clock speed up at a lower voltage. ![]() I assume I can do that by lowering the power curve a little bit to drop the max Mhz and then undervolting it so it can run stable at that speed? Am I getting this right? I want to undervolt my RTX3090 (non Ti) in order to get it to use a little bit less power (50 Watts less would be ideal).
